0012 Description: Number of seconds the SCSI layer will wait after a transport
0013 layer error has been observed before removing a target port.
0014 Zero means immediate removal. Setting this attribute to "off"
0015 will disable the dev_loss timer.

0021 Description: Number of seconds the SCSI layer will wait after a transport
0022 layer error has been observed before failing I/O. Zero means
0023 failing I/O immediately. Setting this attribute to "off" will
0024 disable the fast_io_fail timer.

0037 Description: Number of seconds the SCSI layer will wait after a reconnect
0038 attempt failed before retrying. Setting this attribute to
0039 "off" will disable time-based reconnecting.

0051 Description: State of the transport layer used for communication with the
0052 remote port. "running" if the transport layer is operational;
0053 "blocked" if a transport layer error has been encountered but
0054 the fast_io_fail_tmo timer has not yet fired; "fail-fast"
0055 after the fast_io_fail_tmo timer has fired and before the
0056 "dev_loss_tmo" timer has fired; "lost" after the
0057 "dev_loss_tmo" timer has fired and before the port is finally
0058 removed.
